Beef Stir Fry with Vegetables is a quick and tasty meal that brings together tender slices of beef with a colorful mix of crunchy veggies. In just 30 minutes, you get a dish full of flavor, thanks to a simple sauce that’s both slightly sweet and savory. It’s a great way to enjoy a satisfying dinner without spending hours in the kitchen.
I love how easy it is to customize this stir fry—you can use whatever vegetables you have on hand, like bell peppers, broccoli, or snap peas. I usually marinate the beef briefly to make it extra tender and juicy, which makes a big difference. Plus, it comes together really fast, so it’s perfect for busy weeknights when you want something homemade but don’t have a lot of time.
My favorite way to serve this stir fry is over a bed of steamed rice or noodles to soak up the sauce. It’s always a hit with family and friends, probably because it feels fresh and satisfying all at once. I find myself making extra just so there are tasty leftovers for the next day!
Key Ingredients & Substitutions
Beef: Sirloin or flank steak works best for stir fry because they’re tender and cook quickly. If you prefer, try skirt steak or even thinly sliced chicken or tofu for a lighter option.
Soy sauce, oyster sauce, and hoisin sauce: These add a great balance of salty, sweet, and umami flavors. For a gluten-free version, use tamari instead of soy sauce and check for gluten-free oyster sauce.
Vegetables: Broccoli, bell peppers, mushrooms, and onions give crunch and color. Feel free to swap in snap peas, carrots, or zucchini based on what you have or like.
Cornstarch: Coating the beef with cornstarch helps give it a nice sear and a silky sauce texture. You can use arrowroot or potato starch if you prefer.
How Can I Make Sure the Beef Stays Tender and Juicy?
Here’s how to keep your beef tender in this quick stir fry:
- Slice thinly against the grain. This shortens muscle fibers, making the meat easier to chew.
- Marinate briefly with soy sauce and cornstarch. This helps protect the beef and creates a smooth texture.
- Use high heat and cook quickly. Sear the beef just until browned, then remove it so it doesn’t overcook while you stir-fry the veggies.
- Add beef back at the end to finish cooking gently with the sauce, keeping it juicy and tender.
Following these tips will help you get perfectly cooked beef every time, even in a fast 30-minute meal!
Equipment You’ll Need
- Large skillet or wok – I prefer this because it heats quickly and gives a good sear with lots of space for tossing ingredients.
- Sharp knife – makes slicing the beef and vegetables easy and safe.
- Cutting board – essential for prepping all ingredients in one tidy spot.
- Small bowls – handy for mixing sauces and marinating.
- Measuring spoons and cups – help keep your flavors balanced and consistent.
Flavor Variations & Add-Ins
- Shrimp or chicken – swap or mix in for a different protein that cooks quickly like beef.
- Different veggies – use snow peas, carrots, or zucchini to suit your preference or what’s in your fridge.
- Extra spice – add crushed red pepper flakes or a dash of hot sauce for more heat.
- Hoison or peanut sauce – stir in for a richer, nuttier flavor twist.

Time You’ll Need
This delicious beef stir fry comes together in about 30 minutes. You’ll spend 10 minutes marinating the beef, about 10-15 minutes cooking the beef and vegetables, plus just a few minutes tossing everything with the sauce until perfectly cooked and flavorful.
Easy Step-by-Step Instructions:
1. Marinate the Beef:
In a bowl, mix the thinly sliced beef with 1 tablespoon of soy sauce and cornstarch. Stir well so every slice is coated. Let it sit for 10 minutes—this helps tenderize the beef and gives it a nice sear later.
2. Mix the Sauce:
In a small bowl, combine the remaining 1 tablespoon soy sauce, oyster sauce, and hoisin sauce. Set this tasty sauce aside for later.
3. Cook the Beef:
Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the beef in a single layer and cook for 2-3 minutes, until the edges turn brown but the beef is not fully cooked. Remove the beef and set aside.
4. Stir-Fry the Vegetables:
Add the remaining 1 tablespoon oil to the skillet, then toss in minced garlic and grated ginger (if using). Sauté for about 30 seconds until fragrant. Add chopped onion, bell peppers, broccoli, and mushrooms. Stir-fry for 4–5 minutes, until vegetables are brightly colored and tender-crisp.
5. Combine and Finish Cooking:
Return the seared beef to the skillet with the vegetables. Pour the prepared sauce over everything and toss well to coat. Cook for another 2 minutes, stirring constantly, until the beef finishes cooking and the sauce thickens a bit.
6. Season and Serve:
Add salt, black pepper, and red chili flakes to taste. Sprinkle chopped green onions on top just before serving. Enjoy your bright, flavorful stir fry over steamed rice or noodles for a quick and satisfying meal!
Can I Use Frozen Beef for This Stir Fry?
Yes, but be sure to fully thaw the beef in the refrigerator overnight before marinating and cooking. This helps ensure even cooking and the best texture.
Can I Make This Stir Fry Ahead of Time?
You can prep the vegetables and marinate the beef a few hours ahead. Cook everything fresh when ready to serve for the best flavor and texture.
How Should I Store Leftovers?
Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet or microwave to avoid overcooking the beef.
What Vegetables Can I Substitute?
Feel free to swap in veggies like snap peas, carrots, zucchini, or baby corn depending on your preference or what you have on hand.
